直流超导输电线的主要优点是即使在低压电力传输中也具有低损耗。当传输长度较长时应实现。因此，我们讨论和分析石狩项目的热流体动力学性能的一个方面，并显示了一个100公里的输电线路的设计。同时，我们还讨论了电缆设计，对于500 MW输电，电缆的额定电压低于50 kV。这是直流电网最重要的优势之一，因为我们可以省略超高压变电站，一次和二次变电站，我们可以直接将发电站连接到配电站。最后，我们或许能够降低电网的建设和运营成本。
Main merit of the DC superconducting power transmission line is low loss even in low voltage power transmission. It should be realized when the transmission length is long. Therefore, we discuss and analyse an aspect of thermo-hydrodynamic performance of Ishikari project, and show one design of 100 km transmission line. At the same time, we also discuss the cable design and the rated voltage of the cable is lower than 50 kV for 500MW transmission. This is one of the most important advantages to make the DC power grid because we can omit an ultra-high voltage substation, the primary and the secondary substations and we can connect the power stations to the distribution stations directly. Finally, we may be able to reduce the construction and operation costs of the power grid.
